Specification of Letters Patent.

Patented Feb. 20,1911

Original application filed August 7, 1916, Serial No. 113,572. Divided and this application filed October 28,

1916. Serial No. 128,350.

To all whom it may concern:

Be it known that 1, JOHN C. F. Mo- CAULEY, a citizen of the United States, residing at Fowler, in the county of Meade and State of Kansas, have invented certain new and useful Improvements in Buffers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in buffers and is a division of my copending application Serial No. 113,572, filed August 7, 1916, for improvements in harvesters; and it is an object of the invention to provide a novel and improved arrangement of parts whereby two portable bodies are adapted to cooperate and whereby said bodies are protected against injury one by the other when in cooperating relation.

The invention consists in the detailsof construction and in the combination and arrangement of the several parts of my improved buffer whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a fragmentary top plan view illustrating a main header and a supplemental header constructed in accordance with an embodiment of my invention;

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1; and

Fig. 3 is a fragmentary view in perspective illustrating the bumper herein embodied and carried by the supplemental header.

As disclosed in the accompanying drawings, F denotes the frame of a main header H which includes the draper or carrying belt D, the same being of any well known construction and which is generally employed in connection with a threshing machine (not illustrated.) The portion of the frame F rearwardly of the back shield or screen S supports the endless conveyer C adapted to be suitably driven, as indicated at 1', from a movable part of the header H or the threshing machine or in any manner which best suits the requirements of practice.

The conveyer C travels between the side boards 2 and delivers within the chute 3 discharging upon the draper or carrying belt D. Said endless conveyer C is preferably positioned at a point substantially midway of the header H. The outer side board 2 is provided with the inwardly disposed apron i as is also the rear end board 5 so that the grain discharged from the supplemental header H may be properly delivered upon the conveyer C. The second or inner side board 2 is preferably provided with the upstanding guard or shield 6 of canvas or other suitable material for a purpose which is believed to be self-evident.

The header H is of conventional construction and is adapted to be operated independently of the header H preferably by draft animals and in a well known manner, and the draper or carrying belt D of the header H delivers upon the elevating mechanism E and when the header H is in assembled relation relative to the header H the elevating mechanism E discharges upon the conveyer G hereinbefore referred to, and in order to facilitate such discharge the upper or outer end of the elevating mechanism E is provided with the downwardly eX- tended hood or chute A so that the possibility of any of the grain becoming indiscriminatel y scattered or lost is lessened.

Disposed along the upper marginal portion of the outer side board 2 is a rail or rod 7 preferably of metal and circular in cross section and with which is adapted to contact the rollers 8 carried by and positioned beneath the opposite sides of the elevating' mechanism E so that any relative independent movement of the headers H and H when in assembled or cooperative relation will not result in injury to either the conveyer C or the elevating mechanism E.

I have also found it of particular import to provide the outer portion of the frame F with the inwardly disposed stop or arm 9 preferably of metal and with which the bumper B carried by the inner end portion of the header H is adapted to contact so that the headers H and H are protected against injury should the header H be caused to advance sufliciently as to come into contact with the header H.

As herein embodied, the bumper B comprises an elongated metallic rod secured to the inner end of the forward marginal portion of the header H and having its lower end portion disposed upwardly on a predetermined curvature. Interposed between the upper end portion of the bumper .B and an adjacent stationary part of the header H is the rigid brace member 10. A second rigid brace member 10 is interposed between the bumper B at a point above but in close proximity to the curved portion thereof and a stationary part of the header H at the lower portion thereof. 1O denotes a third brace member interposed between the lower portion of the bumper B and a portion of said bumper above but in close proximity to the curved part thereof, as is particularly illustrated in Fig. 3.

From the foregoing description, it is thought to be obvious that a header constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this end portion arranged on a predetermined curvature, a brace rod interposed between the upper portion of the bumper and the body, a brace rod interposed between the bumper at a point adjacent the upper part of its curved portion and the body, and

a brace rod interposed between the lower portion of the bumper and a portion of the bumper above but in close proximity to the curved portion thereof.

In testimony whereof I hereunto aliix my signature in the presence of two witnesses.

JOHN C. F. MCCAULEY.
